BACKGROUND OF THE DISCLOSURE 1. Technical Field

The disclosure generally relates to devices used to contain fires and cook over fires. More particularly, the disclosure relates to an outdoor fire containment device commonly known as a fire pit and to a holder for an accessory post that allows accessories such as grills and kettles to be used over a fire. Specifically, the disclosure relates to the air inlet configurations for the fire pit, the configuration of the grill support post, the configuration of the grill carried by the grill support post, a holder for the grill support post, and the configuration of the legs for the fire pit.

2. Background Information

People enjoy burning small camp fires in their backyards. These fires are used for general enjoyment and for cooking. One drawback with a backyard campfire—especially one made from a soft wood or a wood containing water—is the smoke generated from the fire. The smoke can infiltrate the owner's house and neighbors' houses. This problem has led some cities and communities to completely ban backyard campfires. Another issue is positioning a grill or container at the proper location above the flames for cooking a particular food. Some people use fire pits to control and contain their camp fires. In some communities, the use of a fire ring or fire pit is mandatory. A popular fire pit configuration has an airflow chamber between the exterior walls of the main body wherein air is heated before being introduced at the top of the burn box. This helps to reduce smoke produced by the fire. Although various versions of the reduced smoke fire pit are known, there remains room for improvement.

DETAILED DESCRIPTION OF THE DISCLOSURE

An exemplary configuration of a fire pit device of the disclosure is indicated generally by the numeral 2 in the accompany drawings. Device 2 generally includes a main body 4 supported above the ground by a plurality of legs 6. An overhanging grilling flange 8 is disposed about the top of main body 4. Flange 8 may be used to support cooking tools, grills, or as a protective bumper. Flange 8 can be made from 304 stainless steel to also function as a grilling surface itself. Device 2 provides a safe and convenient place for one to burn a small fire that can be used for cooking or general enjoyment. The fire is burned in the fire box cavity defined by main body 4. Device 2 may be made from any of a variety of fire-resistant materials. Main body 4 can be fabricated from steel and protected with a heat-resistant paint.

Device 2 is configured to reduce the amount of smoke produced by the fire burning in main body 4. The reduction in smoke is achieved by supplying heated combustion air to the top of the fire. This air is supplied through a plurality of upper air supply openings 10 defined by main body 4 adjacent the upper end of main body 4. Openings 10 may extend about the entire circumference of body 4. Air is supplied to upper air supply openings 10 through an air supply duct 14 that extends from an inlet disposed adjacent the lower end of main body 4 to openings 10. In the exemplary configuration, duct 14 is defined by inner 16 and outer 18 concentric sidewalls of main body 4. In one configuration of device 2, air supply duct 14 is disposed about the entire circumference of main body 4 with only a plurality of supports 20 interrupting the air flow through duct 14. Supports 20 are aligned with legs 6 and extend from the bottom wall 22 of main body 4 out to outer concentric wall 18. Supports 20 maintain the spacing between walls 16 and 18 but allow inner sidewall 16 to move up and down with respect to outer sidewall 18. In another configuration, duct 14 may be divided into a plurality of adjacent or spaced ducts. Positioning air duct 14 along the sidewall of main body 4 allows the air flowing up through duct 14 to be heated before it exits duct 14 to aid the combustion.

The lower ends of sidewalls 16 and 18 are spaced and not connected to define the inlet of duct 14. The upper ends of sidewalls 16 and 18 are joined together by flange 8 so that openings 10 define the outlet of duct 14. In another configuration, the lower ends of walls 16 and 18 are joined and a plurality of inlets are defined. When a fire is burning in main body 4, inner sidewall 16 is heated to draw air into the inlet where it is warmed. The warmed air rises within duct 14 and exits through openings 10 to the top of the fire. Flange 8 projects radially inwardly over the openings 10 to form a lip that helps to direct air from openings 10 toward the middle of the fire. The warmed air assists the combustion and thus reduces the amount of smoke produced by the fire. When cool, flange 8 can be tilted inwardly slightly such that its inner edge is lower than its outer edge. When device 2 is in use and the fire box is loaded with fuel and the elements of device are hot, the fire box defined by inner wall 16 and bottom wall 22 move downwardly causing flange 8 to tilt downwardly more as shown in FIG. 10. The weight of the fuel and the fire box provide a downwardly force. When cool, the inner edge of flange 8 is either the same height or only about ⅛ inch lower than the outer edge of flange 8 but when device 2 is in use and hot, the inner edge can move down to be ¾ inch lower than the outer edge of flange 8. This movement helps drain grilling juices inwardly instead of out over the outer sidewall 18 and onto the ground supporting device 2. One configuration has an inner flange opening of nineteen inches with an outer flange diameter of twenty-three and a half inches to provide a searing surface on flange 8 of 130 square inches. This configuration is fifteen inches tall. Another configuration has an inner flange opening of twenty-four inches with an outer flange diameter of twenty-nine and a half inches to provide a searing surface on flange 8 of 230 square inches. This configuration is also fifteen inches tall.

Main body 4 is provided in the form of a cylindrical cup with inner sidewall 16 forming a right angle with the bottom wall 22 of main body 4. The height of main body 4 is about half of the diameter with the lip formed by flange 8 extending inwardly about a half inch to three inches. In one configuration, the height of main body 4 is eight to eighteen inches with the diameter being eighteen inches to thirty-six inches. These dimensions have been found to provide desirable results with the air supplied through openings 10 being radially close enough to the center of the fire to reducing the amount of smoke produced by the fire.

Each leg 6 has a lower portion that extends below bottom wall 22 and an upper portion that extends along outer wall 18 to engage the underside of flange 8. Legs 6 position bottom wall 22 above the ground and stiffen main body 4. Legs 6 also maintain the centered position of the fire box by engaging inner sidewall 16 and allowing it to slide up and down along legs 6. Each leg 6 includes an outer leg wall 24 and leg sidewalls 26 which all extend from under flange 8 to the bottom end of leg 6. Leg sidewalls 26 can be welded to outer sidewall 18. As an alternative or in addition to welding, a plurality of tabs 27 project from each leg sidewall 26 through outer sidewall 18 where they can be bent to hold leg 6 in place, welded, or bent and welded. Tabs 27 can be press fit or snap fit through the openings defined to receive them. Each leg 6 also includes a foot wall 28 that projects radially inwardly from the lower end of outer leg wall 24. Foot wall 28 engages the ground upon which device 2 is disposed. An inner leg wall 30 projects upwardly from the inner end of foot wall 28. Inner leg wall 30 limits the collection of dirt, sand, or gravel on top of foot wall 28 and stiffens leg 6. Legs 6 can be formed from a single integral piece of material or from a plurality of pieces welded together.

The lower portion of each leg sidewall 26 is enlarged to at least match the leg depth defined by foot wall 28. These lower portions can be integrally formed with leg sidewalls 26 or can be formed by attaching additional lateral leg walls 32. A slot 34 is defined at the upper junction of each lateral leg wall 32 and each leg sidewall 26. The lower edge of outer sidewall 18 is received in slot 34 to further connect leg 6 to main body 4 and to stiffen device 2. In another configuration, lateral leg walls 32 define slots for each of outer sidewall 18 and inner sidewall 16. As shown in FIGS. 7-9, the inner edges 33 of lateral leg walls 32 engage inner sidewall 16 but do not support it from below such that inner sidewall 16 and bottom wall 22 can move downwardly when device 2 is in use.

An air inlet assembly 40 is carried by bottom wall 22 inside main body 4. Air inlet assembly 40 evenly distributes inlet air to the fire while limiting clogging from ash. Air inlet assembly 40 includes a plurality of open arms 42 that radially extend outwardly from a central joint. The outer end of each arm 42 is open to define first air inlets 44. These first air inlets 44 have the same width and height as the openings defined by open arms 42. These first air inlets 44 are substantially parallel (they directly face) the lower end of inner sidewall 16. First air inlets 44 are closer to inner sidewall 16 than the width of open arm 42. These first air inlets 44 thus distribute inlet air to the outer perimeter of the fire. Spaced second air inlets 46 are defined along the length of the top portion of each open arm 42. Second air inlets 46 are raised up above the upper surface of bottom wall 22 to limit clogging by ash formed by burning fuel. Each second air inlet 46 is formed by bending a portion of the sidewall of open arm 42 upwardly which provides an overhang 48 to limit the entrance of ash into open arms 42. The plurality of second air inlets 46 evenly distribute inlet air below the fire. Air openings 50 and 52 are defined by bottom wall 22 to deliver air from below device 2 into assembly 40. The air is pulled under and along the heated assembly 40 so that it is preheated before being used in the combustion.

An accessory post 60 can be selectively carried by and removed from main body 4. Accessory post 60 can be used to support a cooking grill 62 or a hook for a hanging pot or for supporting a pot and winch assembly. When using accessories such as grill 62, it is desired that accessory post 60 is locked in place and does not rotate with respect to main body 4. In this configuration, the bottom portion of accessory post is inserted through flange 8 and into a post support sleeve 63 secured to main body 4 inside air supply duct 14 at the location of one of legs 6. Sleeve 63 receives post 60 in a sliding relationship that allows post to slide in and out of sleeve 63, but limits lateral movement. The lower end of accessory post 60 is disposed inside sleeve 63, extends below sleeve 63, or extends all the way down and engages support 20 or a portion of leg 6. When locked in place, one or more locking projections 64 engage one or both of sidewalls 16 and 18 to lock the rotational position of post 60 with respect to main body 4. Locking projections 64 sit on top of sleeve 63. Locking projection 64 is also disposed under flange 8 so post 60 cannot be unintentionally lifted while in use.

In this configuration, locking projections 64 are provided by a pin or dowel disposed through post 60. Locking projections 64 also can be formed by welding tabs to the exterior of post 60. The top of sleeve 63 is spaced down far enough from the lower surface of flange 8 to provide room for locking projections 64 to ride on the upper end of sleeve 63. Flange 8 defines a post opening 66 that includes open ears 68 sized to allow locking projections 64 to pass through flange 8. The user inserts post 60 into opening 66 with locking projections 64 aligned with ears 68 as shown in FIG. 4. Post 60 is moved downwardly until locking projections 64 engage the top of sleeve 63. The user then rotates post 60 one direction or the other as shown in FIG. 5 until one or both of locking projections 64 engages sidewalls 16 and 18. A lock collar 70 is slidably carried on post 60 above locking projections 64. Lock collar 70 has two locking fingers 72 that project down along post 60. When locking projections 64 are under flange 8 and rotated into engagement with sidewalls 16 and 18, lock collar 70 is slid down onto flange 8 to position locking fingers 72 through open ears 68 in alignment with locking projections 64 to prevent post 60 from rotating back to a position where locking projections 64 are aligned with ears 68. Lock collar 70 includes a handle 74 that projects rearwardly behind post 60 to keep it cooler so post 60 can be unlocked and removed after cooking.

Grill 62 includes its own handle 80 and locking screw 82 that allows it to be selectively locked and rotated with respect to post 60.

In some situations, the owner of accessory post 60 and cooking grill 62 desire to use these with a camp fire that is not built inside device 2. For example, the owner may be camping at a remote location where it is inconvenient to bring along device 2. The disclosure provides an exemplary post holder 102 that secures accessory post 60 in the ground 104 next to a camp fire location 106 so that cooking grill 62 and/or a kettle hook 108 can be used to prepare food. Driving accessory post 60 directly into ground 104 can yield a wobbly arrangement especially when relatively heavy items are placed on cooking grill 62 which is cantilevered over the fire.

Post holder 102 generally includes a hollow main tube 110 with a pointed lower end 112 that allows it to be driven into ground 104. Main tube 110 is sized to slidingly receive accessory post 60. Pointed lower end 112 is closed to prevent dirt from filling main tube 110 when post holder is driven into ground 104. Post holder 102 also includes at least one stabilizing arm 114 projecting away from the upper portion of main tube 110. One to four arms 114 can be used. Two stabilizing arms 114 are depicted in the exemplary configuration. Each stabilizing arm 114 engages ground 104 when post holder 102 is fully driven into ground 104. Stabilizing arms 114 can include downwardly projecting anchors 116 that help stabilizing arms 114 be driven into ground 104. Anchors 116 can be located at the outer ends of arms 114.

Post holder 102 includes a pair of locking flanges 120 that each define an L-shaped locking slot 122 sized to receive one of locking projections 64 that project from accessory post 60. Locking slots 122 project in opposite directions and are aligned with the top of main tube 110 such that locking projections engage the top of main tube 110 and the bottom of locking slots 122 when accessory post 60 is fully inserted into post holder 102. Each flange 120 can define a recess open to the bottom of slot 122 sized to receive the end of a locking finger 72 such that each locking finger 72 will be disposed below locking projection 64 when lock collar 70 is fully seated. When accessory post 60 is fully inserted into post holder 102, locking projections 64 are disposed in locking slots 122 and are held at the ends of slots 122 by locking fingers 72 of lock collar 70 which is carried by accessory post 60. An optional stop 130 can be provided on accessory post 60 to limit the movement of lock collar 70.

Post holder 102 is used by driving it into ground 104 at a location next to the fire over which grill 62 will be used. Post holder 102 is configured to be driven into ground 104 by accessory post 60. First, the user locates post holder 102 and pushes it into ground 104 as far as it can be pushed into ground 104 by hand. The user then turns accessory post 60 upside down as shown in FIG. 11. The user then repeatedly drives accessory post 60 down inside main tube 110 until it engages the closed end of post holder 102 as shown in FIG. 12. The user continues to slide accessory post up and down striking the bottom of main tube 110 to drive post holder 102 into ground 104 until stabilizing arms 114 are driven into ground 104 as shown in FIG. 13. Accessory post 60 is then removed and turned over as shown in FIGS. 14 and 15. The user then slides accessory post 60 down into main tube 110 with locking projection 64 aligned with slots 122 until locking projections 64 engage locking flanges 120 or the top of main tube 110. The user then rotates accessory post 60 as shown by reference arrow 132 in FIG. 16 to position locking projections 64 at the ends of locking slots 122. The user then moves lock collar 70 down until locking fingers 72 slide into the vertical portions of locking slots 122 to block movement of locking projections 64 as shown in FIGS. 17 and 18. The user then connects grill 62 and kettle hook 108 to accessory post 60 where they are ready to use for cooking.

An alternative configuration for a cooking grill is depicted in FIGS. 21-23 and indicated by the reference number 162. Grill 162 includes a grilling grate 164 that defines a plurality of openings. Grilling grate 164 can be formed in a variety of ways such as a welded grid of bars but many of these grilling grates are formed from sections of expanded metal. The round sections of expanded metal are cut from larger pieces which leaves a plurality of sharp metal ends about the perimeter. Although these metal ends can be ground smooth and disposed under a rim as depicted in FIG. 9, the user still contacts these ends when grill 62 is lifted by grasping its perimeter. Cooking grill 162 eliminates the need to grind the metal ends down to smooth ends. Cooking grill 162 provides an outer body member 166 that surrounds the outer perimeter edge of grilling grate 164 and prevents the users from contacting the outer perimeter edge of grilling grate 164 from both above and below. The protection can be understood by viewing FIG. 23. When one lifts grill 162 by grasping outer body member 166 with the user's hands, the hands cannot contact the sharp metal ends disposed inside outer body member 166. Outer body member 166 projects above the upper surface of grilling grate 164 to provide a retention lip to grate 164 to help retain items on grate 164.

In addition to protecting the user from the sharp metal ends of grilling grate 164, outer body member 166 also strengthens grill 162 and helps grill 162 resist bending forces. In the exemplary configuration, outer body member 166 is ⅝ inch outer diameter round pipe provided by metal formed for a pipe but without the seam welded. This is bent into the circular shape and fitted around the outer perimeter of grilling grate 164 and then welded closed and welded to grate 164. Other sizes from ⅜ inch to 1½ inch can also be used. Other cross sectional shapes also can be used. Outer body member 166 supports the outer perimeter edge of grate 164 from below and stiffens grate 164.
